3 Claims.

"My invention relates to weiders goggles, and has among its objects and advantages the provision lof a'goggle construction so designed as to permit simultaneous wearing of correction glasses. "My invention embodies novel means for effectively housing the correction glasses, in addition to embodying novel adjustment lending comfort and convenience to the wearer.

Figure 11 is a detail view of the finger grip for lifting the goggle unit; and

Figure l2 is a sectional viewy along the line Ivi-i2 of Figure 10.

In the embodiment selected to illustrate my invention, I make use of a harness I2 which includes a head encircling band Il and a semi-circular band i6 having its ends secured to the band il. A front band or strap il has one end connected with the band i6 and its other end connected with the band il.

The goggle unit 2li includes cu-p elemental! having appropriate lenses Il of auch properties as to protect the eyes of the wearer against harm from the welding flame or torch. Cups 22 are provided with' suitable padding 26 which lies against the face of the wearer when the goggles are positioned in wearing adjustment, as illustrated in Figure 1. Figures 1 and 2 illustrate the cups 22 as being designed to accommodate the correction glasses 28.

Goggle unit 20 is provided with the usual ilexible joint 30 and carries brackets I2 adjustable longitudinally thereof. Brackets 32 are provided 5s with slots 34 for the reception of screws 36 anchored in the goggle unit. Screws 3l are provided with wing'nuts 8l for nxedly relating the brackets 32 in precise adjusted positions on the goggle unit.

A semi-circular goggle band l0 is pivotally con- 6 nected at l2 with the band. i4. The ends of the goggle band l0 are onset at Il to provide accommodations for spacing washers Il. Goggle band 40 may be pivoted about its axes l2, as illustrated in Figure 4. Figure l illustrates the normal po- 10 sition of the goggle band with the goggle unit 20 in its wearing position for eye protection purposes. Referring to Figure 6, brackets 32 are bent to provide curved bearing portions I8 arranged in frictional relation with curved bearl5 ing portions I0 formed on the ends oi' straps 52. Bearing portions l0 are interconnected through the medium of a plate Bl, while the straps 52 are pivotally connected at 66 with the rightangular anges Il of a plate riveted to the .20 goggle strap 40 intermediate its ends.

Bearing portions 48 are frictionally related to the bearing portions 60 and may be fixedly related thereto through the medium of bolts l2. Washers 6l are positioned between the wing nut 25 86 and the bearing part 48. Bolts 82 are adapted to draw the bearing parts I8 and l0 into fixed relation.

' In Figures 7 and 8 and 6, I illustrate a coiled spring 6l as having one end connected at 10 with `30 the plate M and its other end connected at 'l2 with a lever 1I pivotally connected at 16 with the plate 60. Piate 60 carries a slotted bracket 1B for the reception oi.' a bolt 80 carried by the lever 1l. Bolt 80 includes a wing nut 82 having 35 threaded relation with the holt for clamping the lever 1l in adjusted position on the bracket 18.

Figure 7 illustratesthespring 68 in its normal position, at which time the cups 22 of the goggle unit 20 are resiliently urged against the face of s0 the wearer. Frequently it becomes necessary to shift the goggle unit 20 away from the face of the wearer to secure clear vision. Such adjustment is illustrated in Figure 3, at which time the cups 22 have been pivoted sumciently far away from theA face of the wearer to-permit clear vision downwardly between the cups and the face.

The point of connection 10 betwewen one end of the spring 88 and the plate 5l is to one side of the axis of the bolts 82, and the tension of the 50 spring is such as to urge the end of the springs in the direction of each other. Thus the point of connection 1li with the spring 68 will resiliently urge the cups-22 against the face of the wearer. Th!! llp may be shifted to the position of ll'ig-Y gg screw arranged to abut the plate 00 limitingx the outward pivotal action of the cups 22 about the axis l0.

Goggle unit 20 may be moved to the completely inoperative position of Figure 4 by shifting the goggle strap I0 to the position oi' Figure 4. Preparatory to shifting the strap to the position illustrated, the cups 22 are ilrst moved to the position illustrated in Figure 3 at which time the cups are in the clear of the glasses 20 so that the strap I0 may be pivoted outwardly.

A coil spring 90 is connected with each end oi' the goggle strap 40. Since both springs and connections are identical, the description oi' one will apply to both. Referring to Figure 10, the coil spring 00 includes a, right-angular bend 02 extending through an opening in the oil'set u. The other end of the spring includes a right-angular bend 0l extending through an opening in the offset 00 oi' a strap 90 pivotally connectedat |00 with the band Il. Strap 98 includes a lslot |02 'for the reception of a bolt |04 anchored to the 'band I4. 'Ihe bolt is provided with a wing nut |00 for clamping the strap 08 in adjusted position of the band M. Right-angular bend 02 is so located as to lieslightly above the pivot l2 when the goggle band lies in the position of Figure 10, and as illustrated in Figures 1, 3 and 5.

Right-angular bends 92 and 04 are urged apart by reason of the coiled portion oi the spring. Thus, when the goggle strap I0 is pivoted upwardly for bringing theright-angular bend 02 below the pivot I2, spring90 will exert pressure on the goggle band for yieldingly holding the band in the position of Figure 4. Strap 90 may be secured in different positions for securing precise adjustment of the spring 00. A resilient member |00 is anchored to the strap I8 and includes a right-angular bend ||0 constituting an abutment for the vgoggle band 40 when it is shifted to the normal position of Figure 3.

From the foregoing description of the various parts of the device, the operation thereof will be readily understood. My invention embodies Welders goggles s`o designed as to effectively accommodate correction glasses. The goggles are susceptible of various adjustments to satisfy the needs and convenience of the wearer. 'I'he harness I2 and all other parts of the invention are formed of nreprooi' material. -The cups 22 may be precisely adjusted to the i'ace of the wearer, and the spring 08may be adjusted to lend more or less tension to the spring B8 for lending comfort to the wearer.

Ii' desired, the goggle unit 20 may be pivoted to the'position o1' Figure 5 about the axis of the bolt 02. To make such an adjustment, the wing nuts Il are loosened which permits the goggle unit 20 to be pivoted upwardly for bringing the unit out o! obstructing range of the wearer's eyes. 'rightening of the wing nut 60 will securely support the unit 20 in the position oi Figure 5.

Without further elaboration, the foregoing will so fully lillustrate my invention that others may, by applying current knowledge, readily adapt the same for use under various conditions oi' service.

I claim:
